In India’s Northeast region, only 23.5% of rural households are connected with electricity. To date, only 3 kW comes from biomass gasification in this region. However, this region has plenty of biomass resources. Therefore, electricity generation from locally available biomass through the thermochemical gasification process may be viable in this region where grid-connectivity is not available. This paper presents a techno-economic analysis of biomass gasification for power generation in NE India. An attempt is made to find out the most economical process by comparing different systems, and it is observed that the downdraft gasifier connected with a 100% producer gas engine or dual-fuel engine could be the best option from the economic point of view. Downdraft gasifier connected with 100% producer gas engine with a capacity of 500 kW and 1000 kW can give the Levelized unit cost of electricity (LUCE) as low as $0.05/kWh, which is lower than the existing tariff in NE India comes from hydro- and gas power plants.

在印度的东北地区，只有23.5％的农村家庭通电。迄今为止，该地区仅3千瓦来自生物质气化。但是，该地区有大量的生物质资源。因此，在该地区无法获得电网连接的地区，通过热化学气化过程从当地可获得的生物质发电是可行的。本文介绍了印度东北部地区生物质气化发电的技术经济分析。试图通过比较不同的系统来找出最经济的过程，并且观察到从经济的角度来看，与100％生产者燃气发动机或双燃料发动机连接的下流气化炉可能是最佳选择。
